Abstract: ABSTRACT OF THE DISCLOSURE:           In the polymerization of vinyl chloride, the adhesion of the resulting polymer to the walls can be prevented by previously applying a specific chemical to the inner walls of the polymerization tank and parts of the device to be contacted with the monomer during the polymerization.  This specific chemical is a copoly-condensate obtained by reacting a resol type phenol/ formaldehyde precondensate with a nitrogen-containing compound selected from the group consisting of nitro-phenols, nitrobenzoic noids, nitrobenzenesulfonic acids, aminophenols, aminobenzoic acids and aminobenzenesulfonic acids.

Abstract: ABSTRACT OF THE DISCLOSURE         A process for recovering noble metals from wastes or other materials by electrolysis.  The process takes place in a vessel in the form of an essentially vertical cylinder, the walls of which constitute the anode and which contains at least one cathode arranged at a distance from said walls.  The material including the electrolyte is mixed in said vessel and to the mixture is imparted such a rotary motion that the noble metal particles are transported to the walls of the vessel acting as an anode to bring the noble metals into solution by anodic oxidation.          The process may comprise the further step of destroying cyanides in the electrolyte by reversing the direction of current while maintaining intense mixing in the vessel.

Abstract: ABSTRACT OF THE DISCLOSURE          A sanding device for use with a drill press comprises a drum divided diametrically into half sections.  The drum is covered by a unitary layer of resilient rubber-like material such as neoprene.  The cover hinges the drum halves together along one side of the drum.  When an abrasive sheet has been installed on the device, the two halves are joined together by means of a nut threaded onto a short shaft which projects from each end of the frum.  The upper nut has a metal shaft extending coaxially from the nut and this shaft can be used to attach the device to a drill press chuck or directly to a shaft.  The mechanism for attaching the abrasive sheet includes two slots each of which extends from the diametrical surface of a respective half section.  Each slot extends the length of the drum and is adapted to accommodate one end of the abrasive sheet.  Preferably each slot extends radially outwardly from the centre axis of the drum and is disposed at an angle less than 45 degrees with respect to a drum radius extending along the diametrical surface of the respective drum half away from the hinge formed by the cover.

Abstract: RADIOMETER            Abstract of the Disclosure A radiometer of the switched type has an R.F. switch connecting a detector selectively either to an antenna whose temperature (in terms of noise energy) is to be determined, or to a reference temperature, i.e. a resistive termin-ation. The detector output is passed through an amplifier whose gain is switched between positive and negative values (for example + 1 and - 1) synchronously with the R.F. switch.          The output of the switched gain amplifier is integrated to produce a rising voltage when the gain is positive and a falling one when it is negative.  When it is positive the detector is connected to the antenna.  By means of a zero crossing detector, a counter is started when this voltage crosses zero.  After a fixed period, the R.F. switch and switched gain amplifier are reversed by the counter to cause the voltage to fall in accordance with the temperature of the resistive termination.  The zero crossing detector and a counter measure the time interval until the voltage again crosses zero, such time interval being compared to the fixed period to provide a comparison of the unknown and reference temperatures independent of the gain of the detector, which is a valuable improvement over prior radiometers.  Also, by measuring time rather than voltage, the arrangement facilitates providing a digital output more suitable for storage and transmission of the data than the analog output of prior radiometers.  The instrument, which is relatively simple, rugged and compact, lends itself well to unattended use in monitoring the effect of rain storms on transmission in the 11.7 to 12.2 GHz band employed for satellite communication.

Abstract: ABSTRACT OF THE DISCLOSURE This timepiece comprises a housing having on its face twenty-four, spaced, transparent, similarly-shaped hour-denoting areas arranged in a triangular configuration and identified by numerals 1 through 24.  Mounted in the housing are at least twenty-four illuminable electronic elements each of which registers with one of said hour-denoting areas.  A conventional, seven-segment display device is also mounted in the housing to register with a twenty-fifth area which is located on the face of the housing within the triangularly arranged hour-denoting areas.  An electronic circuit in the housing energizes the electronic elements one-by-one, and successively for one hour at a time in a cycle which repeats once every twenty-four hours.  The illuminated elements represent the particular hour of the day as indicated by the numerals inscribed on the face of the housing.  The electronic circuit also selectively illuminates the seven segment displays to provide a numerical illustration of time selectively in minutes or seconds.

Abstract: ABSTRACT                FITTING DOCTOR BLADES    For fitting a strip-like flexible metal doctor blade into the usual clamp means of a rotary printing machine there is used a guide having first and second stop surfaces which are linear and parallel, and are spaced by the extent by which it is desired that the blade shall eventually protrude from the clamp means.    The blade is abutted against one stop surface, and is then secured in the guide.  The guide, with the blade in it, is then moved to cause the second stop surface to abut against the clamp means, with the protruding portion of the blade inserted into the clamp means.          The clamp means are tightened onto the blade, and the guide is removed.  For a blade consisting of two strip-like parts placed face to face, the guide is provided with a step.  One blade part is abutted against the stop surface, and the other blade part is abutted against the step.

Abstract: ABSTRACT OF THE DISCLOSURE    A pneumatic brake cylinder device employs a pair of dif-ferent sized fluid motors, the pressure chambers of which serve as air storage reservoirs.  The cylinder of the larger fluid motor is formed by the main casting and contains a larger piston, while the cylinder of the smaller fluid motor is mounted to the main casting in coaxial relationship with the larger cylinder and contains a smaller piston having an elon-gated hollow body that is connected at its open end to one side of the larger piston to form a pressure chamber there-between.  The smaller piston fits within the smaller cylinder in spaced-apart relationship therewith to form a pressure chamber delimited by a seal fixed on the main casting for engagement with the piston periphery at any point along its longitudinal axis.  The larger piston cooperates with the larger cylinder to form pressure chambers on opposite sides thereof.    The arrangement provides for a design employing fewer seals and a simplified main casting in which all the passages to the respective pressure chambers are contained.

Abstract: ABSTRACT OF THE DISCLOSURE              METHOD OF IMMUNOASSAY           A biological fluid from a first animal species (e.g. human serum) is assayed for an immunogen therein by mixing with the fluid (Ig-minus-Fc) fragments of an immunoglobulin from a second animal species (e.g. rabbit), the immunoglobulin being immunospecific to the immunogen or another component of the mixture whereby the immunogen can be determined.  Interference can occur from reaction between first animal species antibodies and the said fragments, and in the method of the invention this interference is avoided or overcome, preferably by also including in the mixture different (Ig-minus-Fc) immunoglobulin fragments from the second animal species which react with said antibodies but not with said immunogen.  These different fragments are preferably aggregated.  The method of the invention is particularly applicable to particle agglutination assays.
